Yes, the other flag I gave "-fno-asynchronous-unwind-tables".  According 
to my googling, this is the more important one, but the 
"-fno-unwind-tables" may also help.

There will still be a little bit of tables, from static libraries.  You 
could probably eliminate them with objcopy and the right choices of 
sections to keep and discard, but I have no idea whether the resulting 
binaries will work or not - tools such as the link-loader expect 
binaries to follow the platform ABI.

Note that this only affects the size of the binary file, not run-time 
speed.  And I expect that most of those parts of the binary file will 
not get paged into memory when the program is run, so the cost is just a 
little disk space - not unlike the cost of leaving debug information in 
the binary.
